OmniSwitch CLI Reference Guide

Configures the local address from which this peer will be contacted. This local address can be configured 
for internal and external BGP peers.

ip bgp neighbor ip_address update-source [interface_name]

The 32-bit IP address for this peer. 

The name of the interface.

OmniSwitch 6850, 6855, 9000, 9000E

• This address does not override the router identification for this BGP peer (configured in the

command). It is the address through which this peer can be contacted within this router. The 

router identification for a peer, especially an external peer, may not exist in the local router, but that 
distant peer can still be contacted via this router. This command sets the local address through which 
this distant peer can be contacted.

• The default is restored by entering the command without a IP address.

• The BGP peer is restarted after issuing this command.

• The update-source is not related to the router-id, it specifies the interface to be used for the TCP 

connection endpoint. By default, the nearest interface is selected.
